Objective To observe the instant reactions and relationship of astrocytes(ASs) and neurons(Ns) in rat forebrain after the unilateral tibia and fibula bone fracture. Methods With immunohistochemical triple staining method,the expression of Fos-protein,glial fibrillary acidic protein(GFAP) and tyrosine hydroxydase(TH) were observed. Results Here we showed 1.After the nociception of the treatment,GFAP-like immunoreactive (-LI) ASs exhibited clear character of nuclei distribution in the lateralmedial habenular nucleus(LHb),paraventricular nucleus of the hypothalamus(Pa),supraoptic nucleus(SON),suprachiasmatic nucleus(SCh),bed nucleus of of stria terminalis(BST),central amygdaloid nucleus(Ce) medial amygdaloid nucleus(Me) and cortex;2.The distribution of Fos-LI Ns and GFAP-LI ASs in above nuclei were similar,there were close relationship between Fos-LI Ns and GFAP-LI ASs.3.There were many double-labelled Fos/TH-LI Ns that were surrounded by the GFAP-LI ASs,and formed the neuron-astrocyte complex(N-ASC).Conclusion The ASs as well as Ns of the above nuclei or regions may be involved in instant response and adjustment of the lower extremity bone fracture nociception simultanneously.

Objective To evaluate the safety and feasibility of step-by-step balloon dilatation combined with contineous biliary drainage in treating benign biliary-enteric anastomosis stricture.Methods The clinical data and imaging materials of 49 patients with benign biliary-enteric anastomosis stricture,who were admitted to authors' hospital during the period from January 2008 to March 2014 to receive treatment,were retrospectively analyzed.Before treatment,the diagnosis of benign biliary-enteric anastomosis stricture was confirmed in all patients by color Doppler ultrasound,MRI and/or contrast-enhanced CT scan,endoscopic or DSA-guided anastomosis biopsy.Among the 49 patients,23 patients (study group) were treated with percutaneous transhepatic step-by-step balloon dilatation (the diameter of used balloon was 8 mm initially,then 10 mm balloon was used in the second month,and 12 mm balloon was used in the third month) together with contineous biliary drainage (lasting for 6 months);26 patients (control group) were treated with single percutaneous transhepatic balloon dilatation (balloon diameter of 6 mm or 8 mm) plus biliary drainage (lasting for 6 months).The improvement of clinical symptoms,the incidence of postoperative complications,and the anastomotic patency rate were compared between the two groups.Results Technical success was obtained in all patients.No procedure-related complications,such as biliary tract hemorrhage and perforation,occurred.One week after the treatment,the difference in bilirubin level between the two groups was not statistically significant (P＞0.05).Although the difference in 3-month anastomotic patency rate between the two groups was not statistically significant,the 6-month,12-month and 24-month anastomotic patency rates of the study group were significantly higher than those of the control group (P＜0.05).Three patients in the study group developed recurrent jaundice at 11.2,14.3 and 17.6 months after treatment respectively;MRI and contrast-enhanced CT scan confirmed the diagnosis of anastomotic stricture recurrence,and balloon dilatation together with drainage tube placement had to be carried out again.In the control group,16 patients developed recurrent jaundice within 3.1-17.1 months after balloon dilatation management,among them one patient died of disseminated intravascular coagulation and the remaining 15 patients received balloon dilatation together with drainage tube placement again.Conclusion For benign biliary-enteric anastomosis strictures,step-by-step balloon dilatation combined with persistent biliary drainage is a safe and effective minimally-invasive treatment.

Objective　To provide data support for the prevention and control of melioidosis by analyzing epidemiological characteristics of melioidosis bloodstream infection and antibiotic resistance of its pathogen in Hainan Province from 2012 to 2021. Methods Data was collected from Hainan Antimicrobial Resistance Surveillance System, and WHONET 5.6 software was used to merge and analyze data. Results The case numbers of melioidosis bloodstream infection showed an increasing trend year by year from 2012 to 2021. The ratio of male to female patients was 4.6∶1, with 347 cases (58.91%) of patients aged 40-<60, the age group with the highest incidence. The number of cases from July to November were 424 cases (72.0%). Haikou and Sanya reported the largest case number, with 261 and 116 cases respectively. But there were no case reported from central area including Chengmai, Tunchang, Qiongzhong and Baoting. Burkholderia pseudomallei strains were isolated from both blood and other specimens in 105 of the 589 patients, with respiratory tract and wood specimens being the sites with the highest number of strains isolated other than blood; the resistance rates of Burkholderia pseudomallei to five antibiotics showed no obvious trend of change, with the lowest resistance rate to imipenem among the five drugs at 0.6%, followed by ceftazidime at 2.2%. Conclusion During the typhoon season, elderly, middle-aged male in coastal areas should pay attention to avoid or reduce their contact with mud and water. For patients with melioidosis bloodstream infection, imipenem or ceftazidime should be selected as early as possible for initial treatment.

Objective To investigate the effect of early enteral nutrition combined with probiotics on the nutritional status of patients with severe head injury. Methods Thirty-five patients with severe head injury were randomized into early enteral nutrition group ( control group, n = 18 ) and early enteral nutrition combined with probiotics group (observational group, n = 17). All the patients received enteral nutrition via nasogastric tube within 24-48 hours following admission. Hemoglobin, lymphocyte count,plasma concentrations of total protein, albumin, prealbumin, cholinesterase, and fasting blood glucose were determined before enteral nutrition and at days 8, 15, 21 after enteral nutrition. Arm circumference (AC), triceps skinfold thickness (TSF) and ann muscle circumference ( AMC ) were measured at the same time points. Gastrointestinal reactions as well as the time to first defecation were recorded. Glasgow coma scale (GCS) was assessed. Results There was no difference in terms of hemoglobin, lymphocyte count, plasma concentrations of total protein, prealbumin, and GCS score at each time point between the two groups ( P ＞ 0. 05 ). At day 8 after enteral nutrition, the patients in the observational group exhibited significantly lower level of fasting blood glucose than those in the control group (P ＜ 0.05 ). At day 15,the concentration of plasma cholinesterase in the observational group was significantly higher than that in the control group ( P ＜ 0. 05 ). At day 21, the observational group showed a tendency in increase of plasma albumin level in comparison with the control group( P = 0. 054), and the decrease of AC and AMC was obviously lower than that in the control group ( P ＜0. 05 ) compared with pre-enteral nutrition. The observational group showed less gastro-oesophageal reflux and constipation as well as earlier time to first defecation compared with the control group ( P ＜ 0. 05,0. 01 ). Conclusion Compared with the ordinary enteral nutrition, the enteral nutrition combined with probiotics can attenuate metabolic disorders and improve the nutritional status of the patients with severe head injury.

ObjectiveTo explore the relationship between chronic kidney disease (CKD) and cerebral small vessel disease (SVD) in elderly patients. MethodsOne hundred and fifty-two elderly male CKD patients for experimental group and 158 elderly male for control group were recruited. Demographic data and vascular risk factors were recorded. White matter lesion (WML) was semi-quantitatively assessed by cerebral magnetic resonance imaging (MRI), and lacunar infarction (LI) was also calculated. Results(1) The prevalenees of hypertentsion and diabetes mellitus were higher in elderly CKD patients than those in control group (30. 9% vs. 19.0%, 23.7%vs. 14.6%;both P～0. 05). (2) The percentages of grade 2 and grade 3 WMLs were higher in elderly CKD patients than those in control group (34.9% vs. 24.1%, 25.7% vs. 16.5%;both P<0.05). Prevalence of LI was higher in elderly CKD patients than that in control group (45.4% vs.25.3% ,X2= 13. 70, P<0. 05). The similar Resultswere also obtained except for control subjects with hypertension and diabetes mellitus. (3) The logistic regression analysis showed that age, hypertension and low glomerular filtration rate (GFR) were closely associated with SVD in elderly CKD patients. ConclusionsHypertention and diabetes mellitus are risk factors for CKD in elderly patients. SVD is associated with CKD, and age, hypertension and low GFR may be risk factors for SVD in elderly CKD patients.
